I get factor of safety- (and phi etc for LRFD) what we're talking about is beyond the required factor of safety. OP designed the part using required multipliers, but the department checking the design wanted an extra 10% strength.
- bumby 7y agoThe point I was trying to get at is that in many cases (e.g., those not covered by an industry standard) there is no explicit “required” factor of safety. It’s left up to the discretion of the authority having jurisdiction. So while the design engineer may feel like a factor of safety of 2.0 is sufficient, the AHJ may “require” a 2.2 FOS to sign off
